Structural basis of multistationary quantum systems. II. Effective few-particle dynamics

Abstract

The mutual coupling of electronic multistationary quantum systems realized, e.g., by semiconductor quantum dots is discussed. For local charge-transfer states such coupling can approximately be described in terms of dipole-dipole interactions: the respective renormalized transition frequencies allow for optically controlled conditional switching processes. Two coupled subsystems can in this way perform all the elementary logical operations, including microscopic information transfer. The appropriate architecture for such a quasimolecular computing system is shown to be the distributed computation based on local transition rules. As a simple example a microscopic realization of a one-dimensional one-way cellular automaton with two states per cell and nearest-neighbor coupling is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
